In this episode, Lisa and Mike delve into the complexities of language as it pertains to the field of laser hair removal and skin treatments. They discuss the term "paradoxical hypertrichosis," exploring its definitions and the potential for misinterpretation within the industry. They highlight the importance of precise language when discussing hair growth, treatment effects, and the various parameters involved in laser technology. They also touch on the significance of understanding skin tone versus skin type, emphasising how clarity in terminology can enhance communication and improve treatment outcomes. KEY TAKEAWAYS Clear and precise language is crucial in discussions about hair growth and laser treatments to avoid misunderstandings and misinterpretations. The term "paradoxical hypertrichosis" is often misused. It should refer to hair growth in areas that have not been treated with laser, while many are confusing it with stimulated or synchronised hair growth in treated areas. Treatments like laser hair removal can lead to synchronised hair growth, where previously dormant follicles may start to grow at the same time due to the treatment, rather than indicating paradoxical hypertrichosis. Terms like "strength" or "stronger laser" are vague and can lead to confusion. It's essential to specify parameters such as fluence, energy density, and power when discussing laser treatments. The distinction between skin tone and skin type is important. Skin tone refers to the concentration of melanin in the skin, which affects how it reacts to treatments, while skin type (Fitzpatrick classification) is related to UV radiation response and is not relevant in the context of laser treatments. BEST MOMENTS "Paradoxical hypertrichosis... basically it's hair growth in an area where you didn't have hair growing before." "I believe that everybody that is saying they see this, they are definitely seeing something, but I don't know if they're all meaning the same thing." "You cannot stimulate new follicles, but you can stimulate them into a different phase of growth." "Skin type is your Fitzpatrick, which is how your skin reacts to ultraviolet radiation." "Using the wrong language is just a, to me, it's bad language." ABOUT THE HOSTS Mike began his career in medical lasers in 1986 with a physics degree and a post-grad in bioengineering. He helped develop the scar-free removal of tattoos using a Q-Switched Ruby Laser in Glasgow, and the world's first IPL system. Known well in the industry for his hard truths, no BS attitude and logical answers. As the author of three books, articles for medical journals, a well read blog, a Laser Protection Advisor and contributor to the BMLA, Mike is the Laser Guru. Lisa's claim to laser fame is being Mike's daughter. Growing up with lasers and never avoiding a physics lesson from her Dad, it was natural to enter the industry. Leaving a corporate career with a baby to jump into self employed life came with challenges. Despite that Lisa has been well recognised for her teaching style, practical tips, bringing the compassion to the science, and laser mentoring.
